• San Francisco running back Frank Gore rushed for 131 yards, 92 of those coming in the second half. He became the first running back to rush for 100 yards against Seattle since Washington’s Roy Helu hit that plateau in November 2011.

• Marshawn Lynch rushed for 103 yards, the third time this season he has hit the century mark. In the past 44 games, the 49ers have allowed an opponent to rush for more than 100 yards in three games, and Lynch is responsible for two of those three efforts.

The game wasn’t decided until the fourth quarter, but the play Seattle really wants back occurred in the first. The Seahawks had the ball, second-and-five from the San Francisco 34, and Russell Wilson showed great patience, waiting to throw fellow rookie Robert Turbin the ball on a wheel route down the sideline. Wilson couldn’t have placed the ball any better, and while Turbin was at full speed, he got both hands on the ball but failed to catch it inside the San Francisco 10. In a game in which Seattle never reached the end zone, that really stood out.

Seahawks surprises

• Seattle failed to score in the second half for only the third time in Pete Carroll’s 39 regular-season games as coach.

• Russell Wilson completed only one pass during Seattle’s first four possessions of the second half, and it resulted in a loss of 2 yards.

Quoteworthy

“We moved the ball well early on. We found our way to get down the field, but it wasn’t enough. You keep getting those field goals, it makes it very tough. We need to convert those drives into touchdowns. In this kind of setting it would have been enough to win the football game.” — Seahawks coach Pete Carroll.
